Security Center says that Windows Defender is turned off

    I have Windows Defender running normally on Windows Vista (the task-bar icon
    is showing that Defender is on and running ok) but the Security Center is
    telling me that Windows Defender is turned off and there is a button to turn
    it on. However, when I press the Turn On button (even though I know it is
    already turned on) I get the message: "Security Center is updating
    definitions for Window Defender". After "searching for definitions" I get
    the message: "There are no new definitions available to download for Windows
    Defender". I'd like to solve this because the Security Center icon is always
    showing me that I have a Security Alert.

    I have exactly the same problem. I just installed Windows Vista business
    version. It is annoying. Can we send this problem to Microsoft?

    Please perform the following to resolve your issues.

    Open elevated command prompt and type cd\windows\system32\wbem press enter

    Then type ren repository repository.old and press enter.

    Restart the computer and check your security center again hopefully
    everything should be working there.

    Thanks and Regards

    Can you give me more details and step by step instructions on what I have to
    do please. I'm not very IT literate.
    Thanks.

    Right-click Command Prompt and Run as Administrator. Type the following
    command:

    winmgmt /verifyrepository

    If the system returns "WMI repository is not consistent", run this command:

    winmgmt /salvagerepository

    The first time you run this it will fail. (It will issue stop commands to
    the services causing it to fail. It might take a couple minutes for the
    services to shut down). Run the command again. You actually may have to
    run it 3 times before it finally runs and completes on its own.

    Reboot your system.

    Thanks for the fix. I've been looking for this for months now. It ha
    happened on another computer and I was worried it was a sign o
    malware.

    The second fix works a charm. You need to restart after you run it th
    2 or 3 times for the warning to go away.

    Wahey

    Hi, petar,

    If you have Windows One care installed,
    It and other virus programs turn off Windows Defender,
    since they have there own programs running in its place.

    All it says is WMI repository is consistent, however the security center
    still says the defender is off and i cannot update it. I tried installing the
    32-bit fix and that didn't work either

    I have the same problem. I have not found the suggested fixes to be useful.

    Specificially:
    When Mohit Kapoor wrote > Please perform the following to resolve your
    issues.

    Open elevated command prompt and type cd\windows\system32\wbem press enter

    Then type ren repository repository.old and press enter<
    I tried to do that and was greeted with "Access Denied"
    command:

    winmgmt /verifyrepository

    If the system returns "WMI repository is not consistent", run this command:

    winmgmt /salvagerepository

    The first time you run this it will fail. (It will issue stop commands to
    the services causing it to fail. It might take a couple minutes for the
    services to shut down). Run the command again. You actually may have to
    run it 3 times before it finally runs and completes on its own.

    Reboot your system. <
    But my WMI repository is consistent.

    So, the security panel tells me that Windows Defender is off, but Windows
    Defender tells me it is on.

    I should add that I have have been using this computer for a week and did
    not get the notice that Windows Defender was off until today.

    Please advise.
    Thank you!

    What firewall, anti-virus application or security suite is installed? There
    are some that cause problems which do not appear immediately.

    also if you are running MS Onecare- it will turn off WD when running because
    part of once care has WD built in it

    I, too, am having the same issue. System was fine yesterday ... isn't today.
    I have followed every step outlined in this thread ... even run the
    /salvagerepository command MULTIPLE times with restarts ... no good ... I do
    not have MS OneCare installed. I use Kapersky Anti-virus (Microsoft lists
    this as one of the recommended products). Again, everything has been working
    for months with no issues. Now, Windows security center shows Defender is off
    and their is no anti-virus software installed. Defender itself shows it is
    running, and Kapersky shows that it is running normally. Again, I have
    followed every step suggested in this thread ... I'm still having problems.

    Also, I tried to do a system restore and that failed as well with "The
    writer experienced a transient error. If the backup process is retried, the
    error may not reoccur (ox800452f3)".

    Advice and additional help??

    Jon

    Have pretty much the same problem as Hornet's. Mohit Kapoor's method did not
    work for me. I get a slightly different result from Petar's though and it
    shows like this.......

    C:\>winmgmt /verifyrepository
    WMI repository verification failed
    Error code: 0x80041003
    Facility: WMI
    Description: Access denied


    C:\>winmgmt /salvagerepository
    WMI repository verification failed
    Error code: 0x80041003
    Facility: WMI
    Description: Access denied

    I do not have anti-virus or xxCare One software installed. Previously the WD
    was turned On.
